These pages seem to indicate that Clam AV ships with Ubuntu 12.04. I was sent to the Ubuntu button by ALT-F2 and then searched and found software sources. I was told that changing these settings installed Clam AV.

All that was done but I can't find an Icon or some other way of working with the program and doing scans, updating or doing scans as I do in Norton. How do I know it has loaded and is working?
